Session #16: Homework Solutions Problem #1. For the element copper (Cu) determine: (a) the distance of second nearest neighbors. (b) the interplanar spacing of {110} planes. Solution (a) The answer can be found by looking at a unit cell of Cu (FCC). Nearest neighbor distance is observed along <110>; second-nearest along <100>. The second-nearest neighbor distance is found to be a (Another way of finding it is looking at LN4, page 12). N. Cu: atomic volume = 10-6 m3 / mole = A a3 (Cu: FCC; 4 atoms/unit cell). 4. 10-6 4. a= 3 = 10-10 m 23. 10. a (b) dhkl =. h2 + k2 + 12. 10-10. d110 = = 10-10 m 2. Problem #2. Consider a (111) plane in an FCC structure. How many different [110]-type directions lie in this (111) plane?

→ x = infinity, y = infinity, z = 1/3 This plane does not intersect either the x-axis or y-axis, and intersects the z-axis at z = 1/3. Problem #6 Braquium (Bq) is simple cubic. Calculate the atomic density (atoms/cm2) in the (011) plane of Bq. The molar volume of Bq is 22.22 cm3. Solution (011) looks like this: 1 4 x atoms = 1 atom 4 area ...
